Method for producing ethanol employing colocasia antiquorum fermentation

Abstract

The invention relates to a method for producing ethanol employing colocasia antiquorum fermentation. The method is mainly carried out according to the following steps: 1, chopping down and harvesting fresh and clean colocasia antiquorum; 2, enabling the stem part of the colocasia antiquorum to flow into a stamping machine to crush into a paste porridge body; 3, putting the paste porridge body of the colocasia antiquorum into a high-pressure container to carry out high-temperature and high-pressure curing and sterilizing; 4, putting the cured colocasia antiquorum into a sterile container to cool to room temperature, and adding diastatic enzyme and 20% of wine strain to stir evenly; 5, standing and fermenting a charge cask at 25-30 DEG C for over 7 days; 6, transferring the fermented charge cask to a distillation tower to distill, so as to obtain hydrous ethanol; and 7, adding quick lime to the hydrous ethanol to remove moisture in ethanol, so as to obtain high-purity ethanol. According to the method for producing ethanol by using colocasia antiquorum, the toxicity is reduced by using high-temperature and high-pressure sterilization, ethanol production by fermentation is facilitated, the moisture in the mixed hydrous ethanol is removed by using quick lime, and the method is a scientific method for producing ethanol by using colocasia antiquorum.

Description

technical field [0001] The invention relates to a method for producing high-purity ethanol using wild plant taro as a raw material, and belongs to the technical field of energy industry. Background technique [0002] Ethanol, also called alcohol, is a volatile and flammable organic compound. Because the chemical and physical characteristics of ethanol are similar to those of gas oil, and no smoke is produced after combustion, ethanol can replace gas oil in energy fuels, which is better than gasoline, and Ethanol can be processed and extracted from plants, so ethanol is one of the renewable energy sources that can be exploited by human beings. Wild taro is a perennial evergreen herb, also known as wolf poison, calla lily, etc., commonly found in southern China. The leaves of wild taro are wide and large, the stem is thick and long, and it likes to grow in wet and dark places. Because wild taro plants contain a lot of highly toxic substances, animals and livestock cannot eat...

AI Technical Summary

Problems solved by technology

Although wild taro also belongs to the category of traditional Chinese medicine, it is still used in a small amount as a traditional Chinese medicine because of its internal toxicity, which is difficult to remove. Most doctors do not use Fangdong chamaejasma as a prescription medicine for safety.

Guangdong chamaejasma has also been felled in large quantities and used as raw material for biogas or manure, but because its stems are too thick and contain highly toxic substances, it is difficult for ordinary microorganisms to decompose and decompose it, and it does not produce biogas when it accumulates in the pond for a long time, so it is not suitable for people. Rapid production requirements, so Guangdong wolfbane can grow in large quantities without interference

[0003] The production of ethanol is generally produced by fermenting plants with starch and sugar, such as a large amount of cassava, corn, bagasse, etc., but the sources of these raw materials are all agricultural production species, which require a certain amount of raw material investment
